Ep. 272: Abiogenesis

September 17th, 2012

Episode 306 of 460 episodes

The Theory of Evolution provides a rich explanation for why we see the diversity of life here on Earth. There are so many lines of evidence, from genetic drift to the fossil record. But how did life start? How did things go from a collection of raw materials to the building blocks of life, giving evolution and natural selection a way to take over? That first step, from non-life to life is called “abiogenesis”, and it’s one of the most important questions science can answer.
